Subject: fire protection of steel beams

I am looking for a specification for the 1-hr fire protection of steel beams with a spray-on application.
Also, does anyone know if a steel beam completely concealed in a 1-hr floor/ceiling assembly of wood joists, rated drywall, and concrete flooring over p.w., require additional fire protection, or is it okay as it is completely covered by the other assembly?
